Finding out who people are seems like it would be relatively easy, primarily given that your body registers more than 90% of all perceptible information pre-cognitively. As a human being, your internal navigational system – your intuition and senses – were designed to help “know” what you need to know about anyone within seconds, literally. (And sometimes sooner if you are extremely sensitive and tuned-in.)
Think About it
The last time you met someone, what reaction did your body have to him or her? Your body either opened or closed, expanded or contracted. At this point ,you are somatically interpreting all the bazillion bits of data, like posture, tone, smell, gait, eye movement, and so on, at light-speed and drawing critical conclusions: are they angry, aggressive, combative, kind, relaxed, tense? Basically, you’re attempting to determine if you are safe, and on how many levels: physically, emotionally, etc. In one of Ayn Rand’s books, one of the characters says: “Everything you need to know about someone you will learn in the first 30 seconds of meeting them.” And I would add, “If you are paying attention!”
